Detailed Description
Used to georeference models.
The SoGeoLocation allows to place a non-georeferenced model at its correct location in geospatial coordinates.
VRML X3D SPECIFICATION
- This section describes the expected behavior of the node in a conforming X3D / VRML97 browser application. In some cases, the application is responsible for implementing portions of the expected behavior. Open Inventor viewer classes and IVF classes implement some of the application behaviors.
This section may reference portions of the X3D specification that are not present in this help file. The complete X3D spec is available at http://www.web3d.org .
The SoGeoLocation node provides the ability to geo-reference any models. That is, to take an ordinary model, and to specify its geospatial location. This node is a grouping node that can be thought of as a Transform node. However, the GeoLocation node specifies an absolute location, not a relative one, so content developers should not nest GeoLocation nodes within each other. The geoSystem field is used to define the spatial reference frame and is described in 25.2.3 Specifying a spatial reference frame. The geoCoords field should be provided in the format described in 25.2.3 Specifying a spatial reference frame. The geoCoords field can be used to dynamically update the geospatial location of the model.

ACTION BEHAVIOR
- SoGLRenderAction, SoRayPickAction, SoGetBoundingBoxAction, SoCallbackAction, SoGetMatrixAction, SoGetPrimitiveCount
- GC: Earth-fixed Geocentric with respect to the WGS84 ellipsoid.
- GD: Geodetic spatial reference frame.
An optional second string may be used to specify the ellipsoid using one of the ellipsoid codes that are defined in X3D. If no ellipsoid is specified, then "WE" is assumed (the WGS84 ellipsoid). - UTM: Universal Transverse Mercator
One further required argument must be supplied for UTM in order to specify the zone number (1..60). This is given in the form "Zn", where n is the zone number. An optional argument of "S" may be supplied in order to specify that the coordinates are in the southern hemisphere (otherwise, northern hemisphere will be assumed). - Inventor/geo/SoGeoLocation.h
